The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this is a tough 16-day outlook for Kennebunk Beach. The data is clear: there’s no good surf on offer for the entire forecast period. Every single day through to the end of the month is rated as poor surf conditions, so we’re looking at a prolonged flat spell with nothing to get excited about.
The first few days—starting Wednesday, July 15th—are a total washout. The water is a touch warmer than normal at 67°F, but that’s the only bright spot. With tiny swell around 1ft from the SE and a moderate cross-shore breeze, it’s just not worth paddling out. This remains the same through Thursday and Friday: even smaller waves, down to 0.3ft, with forgettable winds. It’s a real bummer.
We see a slight bump in energy on Saturday, July 18th, with the swell pushing up to 2ft, but the period is a short 4 seconds, so it’s all windswell and no power. Sunday morning, July 19th, actually brings the most size of the first week with 5ft from the SSE, and the combined energy jumps to 186 (moderate), but the wind is a strong onshore breeze at 19 mph, completely wrecking any chance of a clean wave. That’s a kite surfer’s setup, not a paddle surfer’s.
The following week doesn’t get any better. Monday, July 20th, through Tuesday, July 21st, offers 2ft to 5ft, but the wind is always cross-onshore or choppy. The best conditions we see are on Wednesday, July 22nd, and Thursday, July 23rd, with a light breeze and clean conditions, but the swell is still only 3ft with weak energy (69 to 108). It’s clean, but there’s no wave to ride.
The final stretch from July 25th to July 30th is more of the same. The biggest pulse comes late on Monday, July 27th, with a 3ft swell from the SE, a period of 10 seconds, and a combined energy of 228 (moderate), but the wind is again cross-onshore. Clean conditions pop up on the morning of the 28th, but the swell is already dropping. Nothing breaks through as a standout.
Honestly, Kennebunk Beach is a sheltered spot, and this kind of dry run is more normal for the area when the swell direction doesn’t line up. The optimum swell is from the ENE, and we’re getting everything from the SSE and SE. It’s a blank run. Don’t hold your breath—forecasts can change, but right now, there’s nothing to chase.
Stay patient, Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
